To all whom it may concern:

Be it known'that I, HERMANN HILDE, of Rosswein, in the Kingdom of Saxony, Germany, have invented a new anduseful Means for Working Glass, (patented in Germany August 15, 1891, No. 63,540, February 16, 1892, No.69,551,Februaryl9, 1893, No. 72,734; in

England February 28, 1893, No. 4,385, and in Austria-Hungary August 26, 1893, No. 12,69fO andNo. 23,308,) of which the following is a specification.

My invention relates to an apparatus formanufacturing glassware. V The object. ofmy invention is to construct a machine forblow'ing hollow orother glassware which will first drive the molten glass tightly into the mold, thereby completely filling all the smaller convolutions oropenings of the matrix, which would not otherwise be uniformly filled.

The invention consists'in the features, de tails of construction, and combination of parts, which will first be described in connec tion with the accompanying drawings, and then particularly pointed out in the claims.

In the drawings, Figure 1' is a vertical sectional view through the device at right angles tojthe axis of rotation;' Fig. 2, a longitudinal section of the same; Fig. 3, a plan of themold or former; Figs. l to 6, detail views showing the arrangement of the valve -nozzle and Figs. 7 to 10, details of the devices by means of which the glass body may be produced around a core, or without the same, by the aid of an air-blast.

Referring to the drawings, A is a framework or stand provided at its upper end with hearings or journal-boxes a, in which are mounted trunnions B, one of said trunnions being hollow, as shown in Fig. 2, and extending beyond its respective j ournal-box (L, where V it is provided with a hand-wheel b.

The trunnions arefixed to and formed int'egral with a mold-carrier D, which has a central bore extendingeentirely through it, in which bore is located 'ac'ylinder or plug cl, solid at its lower end and provided with a central duct cl at its upper end, said duct opening laterally and communicating with 7 axis of the nozzle.

the central duct or passage in the hollow trunnion, The lower. end of the cylinder d has a collar d fixed to it, which collar enters an annular recess formed in the lower end of the mold-carrier. In this recess, above the said collar d is placed packing material (i of any suitable kind, the said packing being held in place'by the collar (1 The lower end of the cylinder cl projects through a yoke (1 and is provided at each side of said yoke with nuts d, The yoke is secured to the lower end of the mold-carrier by bolts (1 "By adjusting the nuts (1 up or down on the cylinder the collar d may be forced against the packing material as tightly as desired, in order to pervent the escape of compressed air or other fluid around the cylinder at its lower end. The upper end of the mold-carrier is also provided with an annular recess: around the cylinder or plug (1, this recess having a larger diameter at its upper end than at its lower end, the lower or smaller portion of the recess containing packing material 61 and a follower (Z loose upon the cylinder or plug, said follower being above the packing and fitting loosely in the recess.

The enlarged portion of the recess contains a collar d-f, loosely surrounding the plug (Z, which collaris held in place by a joint-plate E, held to the mold-carrier D by screws 6, by means of which the j oint-plate maybe forced downward upon the collar cl", thereby pushing the latter against the follower d and causing the said follower to compress the packing material (1 against the plug 01.

To the upper end of the .plug (1 is secured a valve-nozzle F, having a conical end provided with a coned opening forming a valveseat in which can rest a valve f, provided with a stem f, which passes through, but does not fill, an-air-duct in the longitudinal The lower end of the valve-stem projects into the air-passage d,

and is there provided with wings f forming a stop device, which serves to limit the longitudinal movement of the valve-stem and valve. f v 5 V The upper face of the joint-plate has an upward-proj ectin g base e, whose edge or rim is out under, as shown in Fig. 1, to receive the correspondingly-shaped jaws g of a lower matrix G, formed in two parts, hinged together at 9, Fig. 2, and provided with a pair of handles, each half having a cavity, the two cavities, when the matrix is closed, serving as a mold for the neck of the bottle or other article.

Above the lower matrix is an inner matrix G, having jaws g arranged to engage a projection g on the lower matrix G, said projection having its edge out under or chamfered, as shown, to hold the inner matrix firmly. The said inner matrix is formed in two parts hinged together at g as shown in Fig. 1, and provided with handles g in the usual manner. Outside the inner matrix is an outer matrix G formed in two halves, hinged together, as shown in Fig. 2, the pivot-pin g of the hinge being in line with and integral with the pivot pin of the hinge connection of the lower matrix G. The outer matrix G2 has jaws adapted to engage the chamfered edge of the projection g on the lower matrix in the same manner as the inner matrix. The inner matrix G has a conical opening at its top, in which is removably secured in any suitable manner, as by a bayonet-joint, a cap H, having an elbow-pipe h, to the outer end of which is secured a hose or conductor I, whose other end is secured to a radial pipe K, provided with a stop-cock k, the radial pipe being attached to an axial pipe L, provided with a stop-cock Z, and secured to the outer end of the hollow trunnion B by a coupling Z. The axial pipe L is provided with a nipple 1*, to which a hose or other conductor, leading from a supply of compressed air or steam, is attached.

The frame A has two cross-braces a a arranged one above the other and provided with bearings a through which passes a rod M,

freely movable in a longitudinal direction in said bearings a, the rod carrying a bottomformer or similar mold M at its upper end and resting with its lower end on the inner arm n of a treadle-lever N, fulcrumed at n on the lower cross-brace a.

The operation of the device described is as follows: The inner matrix being secured in place, the cap 11 is removed and the molten glass placed in the said matrix. The cap is replaced and the stop-cock 7c opened to admit the compressed air to the top of the matrix, where it forces the molten glass downward, completely filling the lower matrix and forming the neck of the bottle or other article. The cock Z during this time is closed. After the molten glass is forced into the lower matrix the mechanism is rotated on its trunnions to bring the matrices downward, whereupon the cock 7c is closed and the cock Z opened, admitting the compressed air through the hollow trunnions and plug, forcing the valve f open, and blowing the glass outward to fill the inner matrix. The valve Z is closed and the inner matrix then removed, the treadle being pressed to bring the bottom-mold M to its highest position to support the glass. The outer matrix G is then closed around the article and the valve Z opened to continue the blowing process, forcing the glass against the inner surface of the outer matrix and against the bottom-mold, thus completing the article, which can be readily removed in an obvious manner.

Instead of the matrices above described, I may use other forms for the manufacture of other articles, as will be fully understood by those skilled in the art. Some of these other forms are illustrated in Figs. 7, 8, 9, and 10, which show matrices for the manufacture of articles not requiring any blowing, but which are cast into their respective matrices by the aid of compressed air or other fluid under pressure, thus forcing the glass into all the cavities of the mold.

What I claim is 1. In a glass-working apparatus, the combi nation, with a matrix, of means for supplying fluid under pressure to each end of the matrix in succession, whereby the molten glass is first pressed into the matrix from one end, and then blown from the other end.

2. In a glass-working apparatus, the combination, with a matrix, of a revoluble matrixsupport, and means for supplying fluid to the top and bottom of said matrix, substantially as set forth.

3. In a glass-working apparatus, the combination, with a reversible matrix, of means for introducing fluid to either end of said matrix, substantially as set forth.

4:. In a glass-working apparatus, the combination with a revoluble matrix-carrier having a passage for fluid, and a matrix removably held to the matrix-carrier over the passage exit, of a valve located in said passage, substantially as set forth.

5. In a glass-workin g apparatus, the combination, with a matrix, a matrix-carrier having trunnions and a passage for fluid through one of the trunnions into the matrix, of a nozzle removably secured in the mold-carrier at the termination of said passage, a valve located at the outer end of the nozzle and means for supplying fluid to the passage and to the opposite side of the matrix, substantially as set nati0n,witharevoluble matrix-carrier having In testimony whereof I have signed my a central bore, a plug located within said bore name to this specification in the presence 'ofand provided with a passage, of a matrix two subscribing Witnesses.

above the matrix-carrier, and plug, into which HERMANN HILDE. said passage opens, a Valve located in the Witnesses: passage and packing surrounding the plug, MAX WATTHAI,
